Cancún Seaweed Today — Live Satellite Sargassum Status
Updated June 30, 2026 from Copernicus satellite data — refreshed 4× per day.
Want to know the seaweed conditions in Cancún today? Our live satellite map gives you each Cancún beach a current status — clean, moderate, or avoid — updated today from Copernicus and NOAA imagery, so you can see where the water is clear before you pack the car. Every beach gets a Beach Score from 0 to 100 plus a 7-day forecast, refreshed four times a day. Unlike crowd-sourced photo apps that show you yesterday's guess, we read the actual sargassum signal (AFAI) from orbit — measured, not guessed. When clouds block the view, we tell you that too, instead of pretending. Think of it as a watcher that scans the Caribbean while you sleep and reports each morning which Cancún beaches are worth your day. No invented numbers, no fake reviews — just the satellite, honestly read.
Which Cancún beaches are clean today?
Sargassum never lands evenly along the Cancún Hotel Zone — one stretch can be clear while the next is buried. Our map scores each beach individually so you don't gamble. The northern beaches around Punta Cancún and Playa Caracol, where the coastline turns to face the calmer bay, often hold a cleaner status than the open east-facing shore, but this shifts with wind and current — which is exactly why you check the live status today rather than trust a fixed reputation. Open the map, look for the green (clean) and amber (moderate) markers, and avoid the red ones. Each marker carries today's Beach Score and a short read of conditions, drawn straight from the latest satellite pass — not from a photo someone posted last week.
When does the seaweed clear in Cancún?
Sargassum arrivals come in pulses, not a steady tide. A beach can be hit one morning and noticeably cleaner two or three days later once a band drifts past and crews clear the wrack line. That's why a single status reading isn't enough — you want the trend. Our 7-day per-beach forecast projects how each Cancún beach is likely to move from clean to moderate to avoid, so you can time a beach day or a snorkeling trip for the clearest window. The forecast leans on satellite-tracked sargassum offshore plus current and wind drift. We're honest about uncertainty: the further out the day, the wider the margin, and cloudy passes lower our confidence. We show that confidence rather than hide it.
Where to go instead when Cancún is hit
When the whole Cancún strip shows moderate or avoid, you have nearby options — and the same map covers them. Isla Mujeres, sheltered on its western side, frequently stays cleaner than the mainland's east-facing beaches, and the protected coves toward Puerto Morelos can ride out a pulse the open shore can't. Rather than drive blind, scan the live status across the Riviera Maya and pick the highest Beach Score within your range for the day. Because every location refreshes on the same four-times-daily satellite cycle, you're comparing real conditions side by side, not reputations. The goal is simple: one glance, and you know which water is worth the trip this morning — measured from orbit, reported plainly.
Frequently asked questions
How do I check seaweed in Cancún today?
Open the live map and find your beach — each one shows a current status (clean, moderate, or avoid) and a Beach Score updated today from satellite imagery, so you know conditions before you leave.
How often is the Cancún sargassum data updated?
Four times a day. We pull fresh Copernicus and NOAA AFAI satellite imagery and re-score every beach, so the status reflects recent conditions rather than an old photo or a single daily guess.
Are all Cancún beaches affected the same way?
No. Sargassum lands unevenly, so one beach can be clean while a neighbor is buried. That's why we score each beach separately instead of giving the whole city one rating.
What happens when clouds block the satellite?
We tell you. Cloud cover lowers our confidence for that pass, and we show that rather than inventing a clean reading. Honesty about uncertainty is core to how the Watcher works.
Can I see if Cancún will be clear later this week?
Yes. Each beach has a 7-day forecast projecting how its status is likely to shift, so you can time a beach or snorkeling day for the clearest window. Confidence narrows the further out you look.
How much does access cost?
A one-time PASS, starting at USD 5.99 — no subscription. It unlocks per-beach Beach Scores and the 7-day forecast across Cancún and the Riviera Maya.
